Includes single,dual,and planetary(multi-)head grinders.The motor drives heads equipped with diamond tooling(segments/pads)for grinding.Planetary grinders rotate multiple heads on a plate for more even grinding and higher productivity.Often integrates a vacuum system(or connects to an external vacuum)for dust-free operation.A water attachment allows for wet grinding,reducing dust and cooling the tools.VFD enables soft start and speed regulation.Heavy-duty models are self-propelled to reduce operator effort.

Specified by the number of heads and working width(e.g.,single 12",dual 20",planetary 32").Motor power ranges from 3kW to 15kW or higher.Head speed is adjustable,typically 0-1000 rpm.Abrasives are graded from coarse(#30-#50 metal bonds)to fine(#1500-#3000 resin bonds for polishing).

Used for refurbishing,renovating,and finishing new and old concrete floors.Applications include:floor leveling,old floor renovation,substrate preparation for epoxy floors,and directly creating popular polished concrete floors for commercial buildings.It is the core equipment for achieving high-performance concrete floor finishes.
